Abstract
It has been stated that visual sensory input is dominant when a person is introduced to conflicting sensory inputs. In this study we want to further investigate the interaction effects of the different sensory input by using experiments in which we could separate those sensory inputs. Our experiments are based on the experiments conducted with the tumbling room and the classic 'moving room'. The experiment was set up with tilt angles experienced in daily life, with participants standing freely without any movement restrictions. Participants head movements were recorded, as head posture is automatic and part of the whole postural control. Participants stood on a motion platform that was tilted 14 ° to the left and then 14 ° to the right, with their eyes open, eyes closed and standing in a tilting room on the motion platform. The participants also sat on a modified table that remained upright, while the tilting room was tilted sideways around the participants. While the participants stood in the tilting room the head movements of the participants followed the movement Qf the motion platform. Thus the participants relied on their visual sensory input and vision was dominant In the condition where the participants remained upright and the tilting room was tilted sideways around them, there was almost no head movements of the participants. Participants did not rely on their vision in this condition. It appears that a person determines unconsciously whether the movements of his surroundings are part of his direct environment or not. Based on whether the movement is part of his environment he relies on vision or on other sensory inputs.
